Abstract

518,604. Supply systems for welding arcs. ARMSTRONG, J. J. V. (Vanco Products Co.). Dec. 23, 1938, No. 37406. [Class 38 (iv).] [Also in Group XXII] Welding is effected by producing a discharge preferably of the order of 1,000 volts at 1,000 cycles between the flat surfaces to be welded and then forcing the surfaces into percussive engagement. The bodies 18, 19 to' be.welded are held in chucks 5, 6 and are coupled to a condenser 4 through a variable resistance 7. The condenser is charged in one or two seconds by rectified current from a step-up transformer 1 fed at 110 volts. The discharge is effected in a time of the order of 0.0001 seconds the percussive engagement occurring at the end of the first or second current wave. The chuck 5 is mounted on, a slide 9 and is moved by a pneumatically-operated toggle lever 11. In welding a copper rod to a nickel rod the voltage used is 1,700 and the condenser capacity is 100 microfarads. Discharge occurs with a gap of 0.0135 inches at 9,500 cycles and a current of 20,000 amps.
